Application filed my 31,189`9. 'serial Nofvz'ara. mman.)

To all whom, it mag/ coltccr'm l Be it known that we, ASHER R. JOHNSONand JOSEPH H. LEPSOH, citizens of the United Statesfresiding atCarrollton, "in, the county Baby- Oarriages, of which the following isaY specification.

This invention relates toa jogging device' for a baby-carriage, and theintent and purpose of the same are to impart an easy vertical vreciprocating movement to the carriage-bod y against the resistance ofthe supportingsprings of the latter to produce a soothing effect on ajuvenile occupant of such carriage while the latter is in a position ofrest, thereby providing mechanical means for obtaining a movement of thecarriage-body similar to that usually acquired by manual eiforts, but

Without requiring the attention of any one to' attain the result.

The invention consists of the construction and arrangement of theseveral parts, which will be more fully hereinafter described andclaimed.

In the accompanying drawings, Figure 1 is a side elevation of acarriage, showingthe improved device applied in operative. relationthereto. of a portion of a carriage, showing a slightlymodied form oftheimproved device. Fig. 3 is a detail view in elevationY of thedriverod or reciprocating bar and eccentric. Fig. 4 is a sectional viewthrough the motor and showing the eccentric and a part of the driverodor reciprocating bar.

Similar reference characters are employed to indicate correspondingparts in the several views.

The numeral 1 designates the carriagebody, which is connected torunning-gear 2 byA front and rear springs 3 and 4. The said body may beof any preferred form and also p the running-gear therefor, and torender the operation of such more effective it is necessary that thesprings 3 and 4: or some other analogous spring connection exist betweenthe body l'and the running-gear 2.

The improved attachment comprises a motor 5, which may be of anypreferred form of construction, but preferably of a spring character, asclearly illustrated by Fig. 4, and

Fig. 2 is a sectional side elevation wherein is embodied adriving-spring 6 on an arbor 7, Ahaving a projecting end adapted to beengaged-by a suitable key or winding device. 'From the arbor 7 and bymeans of suitalole'1neshin,f:, gearing a drive-shaft 8 is rotated, andiny connection with one of the 'transmitting-shafts 9 a disk 10 isemployed and keyed thereon. The said disk is surrounded by a break-strap11, having a screwthreaded terminal 12 projecting outwardly through thetop of t-he surrounding box or lcasing 13 of the motorand on saidterminal is a suitable adjusting or Vthumb nut 14, adapted to be turnedto control the pressure of the strap 11 on the disk 10, and therebygovern the movement of the motor either to produce a slower motionthereof or entirely stop the samewhen not desired for use. This is avery simple form of 'motor and is preferred because it can be operatedat points Where an actuating medium, such as electricity, is notaccessible, and is also beneficial for the reason thatthe cost ofrunning the same is considerably less than in devices requiringa primemotive agent for actuating purposes other than the spring.

On the projecting end of the shaft S an eccentric 15 is xed to rotatewith the said shaft and in the present instance is of disk form 4havingaseries of openings 16, radially ar rangedtherein and each seriesvarying in distance from' thecenter of the disk or at similar distancesat various points on the said eccentric. To the said eccentric the lowerend of the drive-rod or reciprocating bar 17 is movably attachedV to anyone of the series of openings 16 that may be desired, and thisparticulardevice may be of solid or continuous form, or, as shown in itspreferred form, comprises a lower socket member 18, having a set-screw19 extending transversely into the same near the upper end and adaptedto adjustably receive the rod 20, which is telescopically fitted intothe lower tubular member 18 to accommodate carriages having elevationsof portions of their bodies above ground or supporting surfaces atdifferent distances. The telescopic form of drive-rod or reciprocatingbar is also exceptionally con- Venient in that it can be reduced tocompact form for storage when not in use. As shown in Fig. 1, the upperend of the drive-rodor IOO reciprocating bar is connected to the clamp21 on the upper portion of the back of the carriage which is used forholding the support of a sunshade, and which serves as an exceptionallyconvenient means of connect` ing the said rod or bar with thecarriagebody.

As shown by Fig. 2, the rod or bar is attached to an eye or otheranalogous device 22, secured to the central under portion of the bed ofthe body l, and the motor 5 is held on a shelf 23, suspended by means ofrods 24 from the frame of the running-gear of the carriage. In thisinstance the weight of the motor will hold it in place on the shelf 23,and this form of the device provides for transporting the entireattachment with the carriage for use at any place desired. In Fig. 1 themotor is rested on the surface of the ground or oor; but in eitherarrangement the operation and result desired to be obtained are thesame.

In operation the motor is released and 1'0- tatcs the shaft 8, which inturn actuates the eccentric 15,and the latter draws downwardly on thedrive-shaft or reciprocating bar and pulls the body 1 of the carriage inthe same direction against the resistance or repulsion of the springs 3and 4, or particularly against such resistance of the springs 4. Thisdownward movement of the carriage-body 1 continues until the lower endof the drive-rod or reciprocating bar passes a vertical line drawnthrough the shaft 8 below the latter. After passing this point the pullon the drive-rod or reciprocating bar is slackened and the springs 3 and4 are free to exert an effort to return to their normal position.Consequently the upstroke of the said rod or bar is automaticallyfacilitated to a great degree by the resilient operation of the springs,and the expenditure of power of the motor is economical. This auxiliaryaction of the springs of the carriage will cause the motor to run agreater length of time under comparative conditions and also make themotion of the body 1 more regular and without jerk or jar that mightarise or ensue if carried on exclusively by the attachments. The strokeof the drive-rod or reciprocating bar may be changed to a faster orslower degree or a longer or shorter stroke in accordance with theadjustment of its lower larly in respect to obviating personal attentionto a carriage containing a child or infant to keep the same in motionand produce a pacifying influence on the occupant. The several parts areof such simple nature that the purchasing price will be reduced to aminimum within the obtainment of any one. The mode of connecting up theattachment to the carriage-body is also within the understanding of anyperson, whether a mechanic or not, and to suit diereut applications itmay be necessary at times to change the proportions, size, and minordetails of construction. Such changes will be made as fully fall withinthe purview of the invention and without sacriicing any advantagesincident thereto.

Having thus described the invention, what is claimed is- The combinationwith a carriage-bod y having a yielding or resilient support, of adriverod or reciprocating bar composed of a lower tubular member and anupper rod telescopically adjustable in the said tubular member, a motorand an exteriorly-exposed disk with a plain surface havingradially-arranged pairsA ASI'IER R.
